OPEN-FIREPLACE HEATER.

SPECIFICATION forming part o f Letters Patent N o. 485,301, datedNovember 1, 1892.

Application filed April 30, 1892.

To @ZZ whom it may concern:

Be it known that I, GEORGE RANDAULPH SCATES, a citizen of the UnitedStates, residing at Knoxville, in the county of Knox and State ofTennessee,have invented a new and useful Open-Fireplace Heater, of whichthe following is a specification. l

My invention relates to heaters for open fireplaces, the objects in viewbeing to provide a heater adapted to be set in an open fireplace and tothoroughly and efficiently distribute its heat throughout the severalcompartments with which it may be connected, which may be adjusted tofit or accommodate itself to various thicknesses of walls, and whichwill secure a complete combustion, or nearly so, of the fuel and willutilize to a greater extent than usual the products of such combustionfor the purpose of heating by radiation.

With these objects in view the invention consists in certain features ofconstruction hereinafter specified, and particularly pointed out in theclaims.

Referring to the drawings, Figure 1 is a vertical transverse section ofa heater embodying my invention. Fig. 2 is a front elevation of thefireplace. Fig. 3 is a similar view of the hot-air box. Fig. 4 is avertical longitudinal sectional view of the grate. Fig. 5 is a similarview of the hot-air box.

Like numerals of reference indicate like parts in all the iigures of thedrawings.

1 designates the chimney of a house; 2, the Second door; 3, the fluewithin the chimney; 4, the chimney-pipe; 5,the chimney-opening; G, thefloor below or first door, and 7 the registeropenings of the second`fioor leadingfrom the ue. The lowerfloor 6 has an opening 7 within thechimney-opening, and communicating with said opening is acold-air-supply pipe S. Vithin the chimney-opening there is located thetire-box 9, and the same terminates at its upper end in a dome, which isconnected to the smoke-pipe 4 by an elbow 10, in which a damper 11 ismounted and controlled by a rod 12, which extends through an openingformed in the facing-frame 13, that surrounds the front of thechimney-openin g 5, and back of which is located the fire-box. Thefacingframe 13 has a register 14, through which radiated heat may pass.

A pair of studs 15 ex- Serlal No. 431,285. (No model.)

tend inwardly from the opposite side walls of the tire-box and throughcurved slots 16, with which the opposite ends or curved terminals 17 ofa U-shaped frame are provided. The U-shaped frame also has a fronttransverse bar 18. 19 designates the grate, which is pivoted at 2O tothe extremities of the terminals 17. .The rear edge of the grate takesunder a series of vertically-disposed angular deliecting-ribs 21,whereby it is supported in position or its movement limited.. Byengaging a poker or other device with the bar 18 it will be seen thatthe grate may be inverted, or partially so, and its contents dumped.Below the grate the back wall of the fire-box is provided with a seriesof air-inlets 22, which insure complete combustion at the rear end ofthe grate and prevent the accumulation of unburned or half-burned coals.

23 designates a hot-air box, and the same is provided with a lower baseportion 24, which communicates with the chimney-opening and receives airfrom the pipe S through an opening 25. The front wall of the base has anopening for the removal of dust in cleaning the box and for theadmission of cold air, which opening may be covered by a door 26. Nearthe upper end of the box a pair of transverse pipes 27 pass entirelythrough from rear to front wall thereof and are open at each end, thefront end being covered by a perforated register-plate. These pipes 27are connect-ed to the hollow base 24 by a pair of vertical pipes 20. Adoor 30 is located at the front side of the box to give access to thepipes and increase the admission of cold air when desired. The backs ofboth the fire-box and hot-air box have pipe-sections 31 projectingtherefrom, and the pipesections of one telescopically connect with thesections of the other, so that, as will be seen, an adjustableconnection between the lire and hot-air boxes is made. From the upperend or dome of the hot-air box to the upper end of the elbow 10, abovethe damper 11 therein, there leads a pipe 32 for passage of smoke.

33 designates a delecting-plate, which extends transversely in the upperend of the tire-box 9. A rod 34 is secured rigidly to the plate, theends of the rod taking over and moving in guides 35, which are curved,as shown, and concentric with pivots 36 of a IOO pair of swinging rodsor arms 37, the upper ends of which are loosely connected to the rod 34.This deflecting-plate 33 may be swung rearwardly, so that it practicallycovers or is interposed between the fire and inner ends of the pipes 31,and thus the heat would be deflected into the room, or by swinging itforwardly a portion of the heat will be permitted to pass rearwardlydirect through the pipes 31 into the hot-air box around and among thepipes 29 and 27, and inally out through the pipe 32 to the smokepipe,and when drawn to the front closes the grate, acting as blower. The coldair passes from the pipe 8 through the base 24, vertically through thepipes 29, thence outwardly into the space or opening 5 of the chimney,where it is joined by more air, which has become heated by contact withthe pipes 31 and back portion of the hot-air box. Some of this heatedair passes laterally through the register-openings 28 into the room,while the rest of it will pass through the register-openings 14 of theroom opposite or up the flue and through the openings 7 of the' secondfioor, and during its passage will be in contact with the smoke-pipe 4,and in this manner the products of combustion are utilized to theirfullest extent, and a constant supply of pure cold air is being heatedand c onducted to the various compartments wit-h which the heater isconnected. Y

Having described my invention, what I claim is 1. In a heater of theclass described, the combination, with the lire-box, of the hot-air boxlocated in rear thereof, the smoke-pipe leading from the upper end ofthe fire-box and communicating with the upper end of the hot-air box,cold-air inlets for the hotair box, transverse pipes through the hot-airbox, vertical pipes leading from the cold-air inlets to the transversepipes, pipes between the fire-box and the hot-air box, and a movabledeflecting-plate pivotally supported below the pipes between the lireand hot-air boxes, substantially as specified.

2. In a heater of the class described, the combination, with thefire-box, the hot-air box, pipes between the same, air-pipes located inthe hot-air box, and smoke-pipes leading from the box, of oppositecurved ways secured to the inner walls of the {irc-box, a shaft havingits ends resting in the ways, a deiiecting-plate connected to the shaft,and arms pivoted concentric to the ways and to the shaft, substantiallyas specified.

5. In a heater of the class described, the combination, with thetire-box having the smoke-pipe, of the hot-air box provided with ahollow base, air-pipes leading from the base to the upper end of anddischarging from the hot-air box, and adjustable pipe-sectionsleadingfrom the backs of the re and hot-air boxes and from the smoke-pipeandtelescopically connecting with each other, substantially asspecified.

6. The chimney having the chimney-opening 5, the internal due havingregister-boxes 7, the smoke-pipe 4, and the lioor 6, having the opening7, and the cold-air pipe 8, communieating with the opening, combinedwith the facing-frame 13, having the perforations 14 and the opening,the hot-air box 9, located in the chimney-opening in rear of the openingin the facing-frame and communicating with the pipe 4 by the elbow 10,the damper 11,10- cated in the elbow, the perforations located in theback of the re-box below the grate, the hot-air box 23, the pipes 31,connecting the same with the fire-box, the pipe 22, connecting the upperend of the hot-air box with the elbow, the hollow base having theopening 25, the transverse pipes 27, located in the hot-air box, and thevertical pipes 29, connecting the hollow base with the transverse pipes27, the latter having their ends opened, substantially as specified.
